Adding Objects to
Versioning-Suspended Buckets

Once you suspend versioning on a bucket, Amazon S3 automatically adds a
null version ID to every subsequent object stored thereafter (using
PUT, POST, or
COPY) in that bucket.

The following figure shows how Amazon S3 adds the version ID of null to an
object when it is added to a version-suspended bucket.

If a null version is already in the bucket and you add another object with the
same key, the added object overwrites the original null version.

If there are versioned objects in the bucket, the version you
PUT becomes the current version of the object. The
following figure shows how adding an object to a bucket that contains versioned
objects does not overwrite the object already in the bucket. In this case, version
111111 was already in the bucket. Amazon S3 attaches a version ID of null to the
object
being added and stores it in the bucket. Version 111111 is not overwritten.

If a null version already exists in a bucket, the null version is overwritten, as
shown in the following figure.

Note that although the key and version ID (null) of null version are
the same before and after the PUT, the contents of the null
version originally stored in the bucket is replaced by the contents of the object
PUT into the bucket.
